Interior Low Plateaus
The Interior Low Plateaus are a physiographic region in eastern United States. It consists of a diverse landscape that extends from north Alabama across central Tennessee and Kentucky into southern Illinois, Indiana, and Ohio. Its natural communities are a matrix of temperate forests, woodlands, and prairies. Setting This is a region of rolling plains and eroded plateaus, with a humid subtropical climate in the south and humid continental climate in the north. It is notable for its extensive karst limestone, which comprise the caves at Mammoth Cave National Park. This region includes a portion of what the U.S. Forest service calls the "Central Hardwood Forest". The region extends from southern Ohio, Indiana and Illinois through Tennessee and central Kentucky and into northern Alabama. Nearly 65% of Kentucky's territory is within the Interior Low Plateaus region, which encompasses an area from the western Appalachian Plateaus to the Tennessee River. It includes the Kentucky Blu ...

Hoosier National Forest
The Hoosier National Forest is a property managed by the United States Forest Service in the hills of Southern Indiana, southern Indiana. Composed of four separate sections, it has a total area of . Hoosier National Forest's headquarters are located in Bedford, Indiana, Bedford, with a regional office in Tell City, Indiana, Tell City. Prominent places within the Forest include the Lick Creek Settlement, Potts Creek Rockshelter Archeological Site, and Jacob Rickenbaugh House. History Hoosier National Forest was first touched by humanity 12,000 years ago, when Native Americans in the United States hunted in the forest. Europeans reached the forest in the late 17th century, and began building villages in the forest. Actual lumbering began in the 19th century, with the cutting of more difficult terrain occurring after 1865. By 1910 most of the area had been cut. In the early 1930s the governor of Indiana pushed for the federal government to do something with the eroding lands that sa ...

Bluegrass Region
The Bluegrass region is a geographic region in the U.S. state of Kentucky. It makes up the central and northern part of the state, roughly bounded by the cities of Frankfort, Kentucky, Frankfort, Paris, Kentucky, Paris, Richmond, Kentucky, Richmond and Stanford, Kentucky, Stanford. It is part of the Interior Low Plateaus ecoregion. "Bluegrass" is a common name given in the United States for grass of the ''Poa'' genus, the most famous being the Poa pratensis, Kentucky bluegrass. Despite its name, Kentucky bluegrass is native to North Africa and was likely introduced around 1600. Geology The Bluegrass region is characterized by underlying fossiliferous limestone, Dolomite (rock), dolomite, and shale of the Ordovician geology, geological age. Hills are generally rolling, and the soil is highly fertile for growing pasture. The Kentucky Bluegrass is bounded on the east by the Cumberland Plateau, with the Pottsville Escarpment forming the boundary. On the south and west, it bor ...

Tennessee River
The Tennessee River is a long river located in the Southern United States, southeastern United States in the Tennessee Valley. Flowing through the states of Tennessee, Alabama, Mississippi, and Kentucky, it begins at the confluence of French Broad River, French Broad and Holston River, Holston rivers at Knoxville, Tennessee, Knoxville, and drains into the Ohio River near Paducah, Kentucky. It is the largest tributary of the Ohio, and drains a basin of . Its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia. Etymology The river appears on France, French maps from the late 17th century with the names "Caquinampo" or "Kasqui." Maps from the early 18th century call it "Cussate," "Mitchell Map, Hogohegee," "Callamaco," and "Acanseapi." A 1755 British map showed the Tennessee River as the "River of the Cherakees."Ann ToplovichTennessee River System, ''Tennessee Encyclopedia of History and Culture'', December 25, 2009; upd ...

Appalachian Plateaus
The Appalachian Plateau is a series of rugged dissected plateaus located on the western side of the Appalachian Mountains. The Appalachian Mountains are a range that run from Nova Scotia in Canada to Alabama in the United States. The Appalachian Plateau is the northwestern part of the Appalachian Highlands physiographic division of the United States, stretching from New York state to Alabama. The plateau is a second level United States physiographic region, covering parts of the states of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Alabama, and Georgia. Geography and physical features The formation of the plateau began during the Paleozoic Era. Regional uplift during this time caused the area to rise altogether without changing the topography of the land. The eastern side of the plateau appears as a mountain range. This false appearance is due to a very steep slope on the eastern side known as the Allegheny Front. The eastern edge i ...

Emma Lucy Braun
Emma Lucy Braun (April 19, 1889 – March 5, 1971) was a prominent botany, botanist, ecology, ecologist, and expert on the forests of the eastern United States who was a professor of the University of Cincinnati. She was the first woman to be elected President of the Ecological Society of America, in 1950. She was an environmentalist before the term was popularized, and a pioneering woman in her field, winning many awards for her work. Life and career Emma Lucy Braun was born on April 19, 1889, in Cincinnati; she lived in Ohio for the remainder of her life. The daughter of George Frederick and Emma Moriah (Wright) Braun, her early interest in the natural world was encouraged by her parents, who took her and her older sister Annette Frances Braun into the woods to identify wildflowers. Braun's mother even had a small herbarium. In high school, Braun herself began collecting plants for study, the beginning of a huge personal herbarium that she assembled over her lifetime, comp ...

Mammoth Cave National Park
Mammoth Cave National Park is a national park of the United States in south-central Kentucky. It encompasses portions of Mammoth Cave, the longest known cave system in the world. The park's are located primarily in Edmonson County, with small areas extending eastward into Hart and Barren counties. The Green River runs through the park, with a tributary called the Nolin River feeding into the Green just inside the park. The cave system has formally been known as the Mammoth–Flint Ridge Cave System since 1972, when a connection was discovered between Mammoth Cave and the even longer system under Flint Ridge to the north. As of 2022, more than of passageways had been surveyed, over 1.5 times longer than the second-longest cave system, Mexico's Sac Actun underwater cave. The park was established as a national park on July 1, 1941, after oft-contentious eminent domain proceedings whose consequences still affect the region. It was named a World Heritage Site on October&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers, and cold (sometimes severely cold in the northern areas) and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermitte ...

Humid Subtropical Climate
A humid subtropical climate is a subtropical -temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia) or oceanic climates (in other continents). It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classific ...

Prairie
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...
